Porting LineageOS to FP2

Switch 4G SIM to 2G and 2G SIM to 4G and back again

For some people this isn’t working in regular Fairphone OS at the moment, so it’ll be interesting to see if it does work in Lineage. If, however, it doesn’t work on Lineage either, maybe the same work-around helps:

Dual sim after marshmallow update?

I’ve found a way round this: Go to SIM cards in settings. Deactivate the sim that you don’t want to be 4G. Then go to More, mobile networks. You should now be able to change the active sim to 4G. After doing this, go back and reactivate the non-4G sim card.
